Nail connection, carrying wheel support 25 are fixed in mounting bracket 21, and bearing wheels carry the prevailing quality of guidance tape.
Limited block 12 is connected by screw to bracket of stop block 11, and bracket of stop block 11 is fixed in mounting bracket 21；?
The both ends of the 19 stroke end of guide rail are mounted on limited block 12, prevent idler wheel 16 in moving process because taking off beyond guide rail 19
Rail.
Transmission mechanism includes motor 4, pinion gear 5, transmission belt 13, gear wheel 12, the bevel gear 11 for manually controlling
And leading screw and nut mechanism.Motor axis connection pinion gear 5 drives gear wheel 12 to rotate by pinion gear 5, and gear wheel 12 and screw rod 18 are
Coaxial fixed, when screw rod rotation, along screw axis to moving back and forth, nut is fixed on mobile bracket 17 nut.
Wherein, when guidance tape 1 is retracted to car, mobile bracket 17 is moved to the end of guide rail 19, and guide pad 7 is mobile at this time
Onto Auxiliary support 20, mobile bracket 17 is moved in Auxiliary support 23, is prevented because the gravity of guidance tape itself is to moving guide rail
Mechanism damages.
Position-limit mechanism is divided into three parts, and first is mechanical position limitation, when mobile bracket 17 is moved to the front end of guide rail,
Carrying wheel support 25 plays position-limiting action, and when mobile bracket 17 is moved to guide rail rear end, stop screw 6 plays limit and makees
With.Second is the limit switch 14,24 for being mounted on track both ends, and when guide pad touches limit switch, motor 4 stops fortune
Turn.Third road is ratchet 9 and counter 8, and when number of teeth mesh reaches certain number on the record ratchet of counter 8, motor stops
Operating.
Mechanism shown in Fig. 1 is center line symmetrical mechanism.Screw rod 18 and bearing 22 are all mounted on the central axes of mechanism.
The part-structure figure hidden under guidance tape is as shown in Figure 2 and Figure 3, and mounting bracket 21 is connected on chassis, guide rail 19 and peace
It fills bracket 21 to consolidate, with guide rail 19 with merging and can roll, mobile bracket 17 is connect idler wheel 16 with idler wheel 16.
One fan hinge of hinge 3 is consolidated by rivet and mobile bracket 17, and another fan is consolidated with guidance tape 1,1 around hinge of guidance tape
The certain angle of 4 hinge axis, to meet the needs of connecting with road surface.
Backplate 2 is installed in 1 two sides of guidance tape respectively, prevents wheelchair from going out guidance tape and causes an accident.
In conclusion it is found that the invention has the characteristics that:
